Logistics Knowledge Base

Welcome to the CXTMS Logistics Knowledge Base — a comprehensive educational resource covering the core concepts and terminology of the freight and logistics industry. Whether you are new to logistics or looking to deepen your understanding of specific transport modes, this knowledge base is designed to help you build a solid foundation.

The Global Logistics Industry​

Logistics is the backbone of global commerce, enabling the movement of goods across continents, oceans, and borders. The global logistics market was valued at approximately $3.9 trillion in 2024 and is projected to reach $5.9 trillion by 2030, growing at a 7.2% CAGR (Grand View Research, 2025). This growth is driven by e-commerce expansion, globalization of supply chains, and increasing demand for fast, reliable delivery.

The industry encompasses multiple specialized sectors:

  • Freight Forwarding ($165-220 billion market, 4.9-5.2% CAGR) — intermediaries that arrange and coordinate transportation across modes
  • Ocean Freight — the dominant mode for international cargo, carrying over 80% of global trade by volume
  • Air Freight — premium speed and reliability, handling 35% of global trade by value despite representing just 1% by volume
  • Trucking — critical for domestic distribution, with the U.S. trucking industry alone valued at $906 billion in 2024
  • Parcel Shipment — small package logistics serving e-commerce, with 23.8 billion packages shipped annually in the U.S.
  • Warehousing — approximately 17 billion square feet of warehouse space in the U.S., supporting storage and fulfillment operations

Logistics employment is robust and growing: the global logistics workforce exceeded 14.5 million people in 2024, with the U.S. Bureau of Labor Statistics projecting 17% employment growth for logisticians from 2024 to 2034 — nearly five times the average for all occupations.

How Logistics Modes Connect​

Logistics is inherently multimodal. Most shipments involve multiple transport modes and handoffs:

Understanding each mode — and how they interconnect — is essential for designing efficient supply chains and managing logistics operations.

What You Will Learn​

Each section covers a major area of logistics operations, explaining industry concepts, standard documents, key terminology, and real-world workflows.

Ocean Freight​

The backbone of global trade, carrying 11+ billion tons of cargo annually. Learn about:

  • Bills of lading and negotiable vs non-negotiable documents
  • Container types (dry, reefer, open-top, flat rack, tank)
  • Incoterms 2020 (11 trade terms governing cost and risk allocation)
  • Port operations, terminal handling, and gate procedures
  • Ocean freight rates, surcharges (BAF, CAF, PSS, GRI, D&D), and contract vs spot pricing
  • Demurrage and detention charges and how to avoid them

Global ocean freight handles 80% of trade by volume, with 842 million TEU (Twenty-foot Equivalent Units) moved in 2024.

Air Freight​

Speed and precision for time-sensitive and high-value cargo, representing 35% of global trade by value. Topics include:

  • Air waybills (MAWB, HAWB) and e-AWB adoption (73%+ globally)
  • ULD types (LD-3, LD-7, PMC pallets) and aircraft compatibility
  • Dimensional weight calculations and optimization strategies
  • Dangerous goods regulations (IATA DGR, 9 hazard classes)
  • Airport operations, acceptance, screening, and ramp handling

Air cargo moved 67 million metric tons globally in 2024, with an average cargo load factor of 47%.

Trucking​

Ground transportation for domestic and cross-border freight. The U.S. trucking industry moved 11.27 billion tons of freight in 2024, valued at $906 billion. Learn about:

  • Bills of lading (BOL), straight vs order BOLs, and VICS standards
  • FTL vs LTL shipping and when to use each
  • Drayage (port-to-warehouse short-haul container moves)
  • Intermodal transport (combining rail and truck for long-haul efficiency)
  • Freight classes (NMFC 50-500) and density-based pricing

Trucking carries 80% of U.S. freight revenue and employs over 3.5 million drivers.

Parcel Shipment​

Small package logistics at scale, driven by e-commerce growth. The U.S. parcel market shipped 23.8 billion packages in 2024, generating $196 billion in revenue. Topics include:

  • Shipping labels (tracking numbers, barcodes, zone routing)
  • Tracking and visibility (carrier APIs, multi-carrier platforms, EPCIS standard)
  • Last-mile delivery (home delivery, BOPIS, lockers, crowdsourced models)
  • Returns management (RMA, reverse logistics, disposition strategies)
  • Rate shopping (carrier comparison, contract negotiation, surcharge optimization)

Last-mile delivery costs represent 53% of total shipping expenses and are growing at 21% annually.

Warehouse Management​

The physical hub of supply chain operations. The U.S. operates 17 billion square feet of warehouse space, with WMS software market growing at 21.9% CAGR to reach $15.95 billion by 2033. Learn about:

  • Warehouse zones (receiving, bulk storage, forward pick, packing, shipping)
  • Pallets and unit loads (GMA 48x40, EUR 1200x800, ISPM-15 heat treatment)
  • Labels and barcoding (GS1-128, LPNs, RFID, 2D barcodes)
  • Receiving and putaway (ASN, directed vs random putaway)
  • Picking and packing (discrete, batch, zone, wave picking; cartonization)
  • Inventory transfers (internal, inter-warehouse, replenishment)
  • Inventory management (cycle counting, ABC analysis, FIFO/LIFO, turnover KPIs)

Average warehouse order accuracy targets 99%+ with pick rates of 80-120 lines/hour (manual) or 300+ with automation.

Customs & Compliance​

Navigating international trade regulations. The global customs brokerage market was valued at $24.7-27.5 billion in 2024, growing at 6.7-7.5% CAGR through 2032. Topics include:

  • HS codes (6-digit Harmonized System for tariff classification)
  • Import/export documentation (commercial invoice, packing list, certificate of origin, ISF 10+2, AES)
  • Customs bonds (single transaction vs continuous, Activity Codes, sufficiency rules)
  • Free trade agreements (14 U.S. FTAs covering 20 countries, rules of origin, USMCA certification)

Proper customs compliance prevents delays, reduces duties through FTA benefits, and avoids penalties.

Freight Forwarding​

The business of moving cargo, coordinating transport, and managing documentation. The global freight forwarding market was valued at $165-220 billion in 2024. Learn about:

  • The role of freight forwarders (carrier vs broker vs NVOCC distinctions)
  • The booking process (rate inquiry, confirmation, shipping instructions)
  • Consolidation (LCL ocean, groupage air, CFS operations, break-even analysis)
  • Quoting and rating (buy vs sell rates, margin vs markup, RMS platforms)
  • Documentation flow (export, transport, and import document lifecycle)

Freight forwarders act as the central coordinator in international shipping, managing carrier relationships, customs brokerage, and end-to-end shipment visibility.
